3 Claims.

This invention relates generally to the art of interior decorating andis particularly directed to improvements in means for securing the edgeportions of rugs linoleum and other floor or wall coverings to thesurfaces to be ornamented or protected. More specifically, the inventionis directed to a molding strip of the extruded type comprising a bodyhaving one or more flanges so disposed as to provide a pocket for thereception of the carpet, linoleum, rubber or other materials to besecured.

The main object of the present invention resides in the provision of amolding strip having a body portion and a flange connected at. one edgethereto,- the flange being curved to provide the same with a claw-likecross section and projected over the body portion to form alongitudinally extending recess for the reception of the carpet, thebody portion of the strip beneath the flange having a retaining ribformed therewith which is sharpened at its edge and inclined toward thejuncture of the body and flange, the rib being embedded in the carpetwhen the free edge of the flange is embedded therein by bending theflange toward the body after the carpet is positioned inthe recess.-, .1

Other objectslof the invention reside in forming the flane'efin suchmanner-as to facilitate the operation'ofbending the same into a carpetsecuring position, making the body portion greater in width than theflange to expose the means for attaching the strip to the floorandcontinuing the surface of the flange downward to cause it toterminate in close relationship to the floor surface to eliminateshoulders which might trip persons walking over the strip.

With these and other objects in view which will appear as thedescription proceeds, the invention consists in the novel formation ofthe strip and the relation of the various parts. as

'best illustrated in the accompanying drawing.

Fig. 1 is a perspective view of a portion of the strip showing th samein position on asurface and having the edge of a section of carpetgripped thereby;

Fig. 2 is a vertical transverse sectional view 'of the strip with theedge of the floor covering positioned between the flange and the-bodyportion of the strip, the flange being in an elevated position prior tothe bending operation;

Fig. 3 is a similar view wherein the flange is bent toward the bodyportion to secure the floor covering in connection with the strip.

'Referring more particularly to the drawing,

the floor covering is to be secured. This surface may be formed fromwood orany other material suitable for forming floors or other buildingwalls. Disposed on the surface I is a section of carpet 2 having abacking portion 3 and a nap 4 projecting upwardly therefrom. Secured tothe surface I is a section of molding 5 forming the subject matter ofthe Present invention.

The molding includes a body portion 6 which,

in this instance, has a wedge-like cross section and is providedadjacent the thinner side thereof with openings l through which screws 8extend to secure the strip to the surface I. A flange 9 projects fromthe opposite edge of the strip over the body portion at an acute angle,the outer surface of the flange extending downwardly over the side ofthe body portion and meeting with the under surface to form a relativelysharp an edge l0.

When the strip is secured to the surface I, the sharp edge is disposedin close relation to the surface and since the flange is inclined withrespect to the body, a feather edge will be produced which will greatlyfacilitate the move- *ment offurniture or other objects over the strip.

The-flange 9 is curved and adjacent the outer portion,fthe' degree ofcurvature is sharply increased to'give the flange a claw-like crosssection, the free edge I I of the flange being relatively sharp anddirected toward the body portion of the strip. The inner surface of theflange is relieved as at I! adjacent the body portion to permit theflange to be bent downwardly toward the body portion after th edge ofthe carpet has been positioned in the groove formed by the body 6 andthe flange 9.

As illustrated in Fig. 3, the bending operation causes the curved outeredge of the flange to be 40 curled under and a smooth rounded surface l5will be disposed at the edge of the floornovering 4. The bendingoperation also causes the sharp .or claw-like edge of the flange to bedirected inwardly into the groove. As the edge of the floor covering ispositioned between the flange and the body portion, the claw II will beembedded in the floor covering and prevent withdrawal thereof from thegroove.

To assist in preventing this withdrawal, the

body portion has a rib l6 formed thereon between the numeral designatesthe surface to which like cross section, the outer sharp edge of the Irib serving to engage the backing of the floor covering 2. Since thebacking is rough, the sharp edge of the ribwill tend to grip the sameand prevent outward movement of the floor covering. When the flange isbent downwardly, the distance between the free edge of the rib and theunder surface of the flange will be less than the thickness of the fioorcovering and the latter will thereby be gripped or pinched therebetween.Since both the claw-like edge of the flange and the barb-like rib aredirected inwardly in the groove, the floor covering will be flrmlygripped and prevented from separating from the strip.

From the foregoing, it will be apparent that a a molding strip has beenprovided which is particularly adaptable for use in binding the ends ofcarpet and rubber runners and securing them to floor or other surfaces.

What is claimed is:

1. An edge molding for securing floor cover-' ings comprising astrip-like body, a curved :flange extending longitudinally of said bodyand connected at one edge thereto, said flange overhanging said body,the degree of curvature of said flange being increased and the thicknessdecreased adjacent its free edge to give the flange a claw-like crosssection, the point of said claw being directed toward said body, andmeans formed with said body beneath said flange for engaging and holdingfloor covering materials positioned between said flange and body, saidflange being capable of movement toward said body to force the claw-likeedge into holding en-,

gagement with the floor covering resting on said body.

2. An edge molding for securing floor coverings comprising a strip-likebody, a curved flange extending longitudinally of said body-andconnected at one edge thereto, said flange overhanging said body, thedegree of curvature of said flange being increased and the thicknessdecreased adjacent its free edge to give the flange and toward said rib.

3. An edge molding for securing floor coverings comprising a strip-likebody having a wedgeshaped cross section, a curved flange projecting fromthe thicker edge of said body over said body and at an acute anglethereto, the degree of curvature of said flange being increased adjacentits free edge to give the flange a clawlike cross section, the free edgeof said flange being relatively sharp, said flange being less in widththan said body, said body having spaced perforations beyond the freeedge of said flange, and barb-like means provided between the free andattached edges of said flange, said barb means being inclined away fromthe thinner edge of said body.
